Abstract: A battery (100) and a battery pack having the same, and an electric vehicle are disclosed. The battery (100) includes: a housing; a cover plate (30) located at an end of the housing; a terminal (40) disposed on the cover plate (30); a pole core (10) located inside the housing and having a tab (20), at least one part of the tab (20) being connected to the terminal (40); and an insulating spacer (50) covering one side that is of the at least one part of the tab (20) and that faces away from the terminal (40).

Abstract: A battery cover plate assembly, a cell, a battery module, a power battery and an electric vehicle are provided. The battery cover plate assembly includes a cover plate, a first pole, a second pole, a flipping member, a scored member, a first conductive member and a telescopic assembly. The second pole includes an upper pole and a lower pole spaced apart from each other. The flipping member is configured to turn over under the action of gas pressure inside the battery and push, by means of the telescopic assembly, the first conductive member to move to break a score, so as to electrically disconnect the upper pole from the lower pole.

The battery includes: a housing; a cover plate located at an end of the housing, the cover plate having a first side region and a second side region arranged in a lateral direction or a longitudinal direction of the cover plate; a terminal disposed on the cover plate, a part of the terminal being located in the first side region, and another part being located in the second side region; a first pole core and a second pole core located in the housing, the first pole core corresponding to a position of the first side region, having a first tab, and connected to the part of the terminal, the second pole core corresponding to a position of the second side region, having a second tab, and connected to the another part of the terminal.

Abstract: The present disclosure is directed to a single-cell battery, a battery module, a power battery, and an electric vehicle. The single-cell battery includes a case, a battery cell, an electrode terminal, and a cover plate. The electrode terminal includes a battery post. The single-cell battery further includes a current interruption device mounted on the battery post. The current interruption device has a conductive member and a flipping member connected to the conductive member for mutual electrical connection. The flipping member and the conductive member can be electrically disconnected from each other under action of air pressure. The conductive member is connected to the battery post for mutual electrical connection. The flipping member and the conductive member are connected to each other by using a boss welded structure. The boss welded structure includes a boss, a connection hole accommodating the boss, and an annular welding spot located between the boss and the connection hole.
